TRADESMANS LIFT.

SPECIFICATION forming part of Letters Patent No. 722,444, dated March 10, 1903.

Application filed December 18, 1901. $erial No. 86,462. (No model.) 1

To all whom, it may concern:

Be it known that I, CHARLES A. BoUcK, a

citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Tradesmens Lifts, of which the following is a specification.

My invention relates to lifts or elevators, and more especially to that class of such devices as are portable or movable from place to place to adapt them to use in store-rooms where it is desirable for the attendant to move in front of the shelves either vertically or laterally while standing upon a platform.

The invention may be adapted to be moved lengthwise of the shelving upon suitable tracks, and the platform may be adapted to be moved vertically relative to the shelving by means of any suitable motive-power medium-as, for instance, liquid or gases, or bothsaid power medium being under the control of the attendant in all positions.

The object of my invention is to produce a device of this kind which will be compact, simple, and efficient; and it consists in the combination and improved construction of the parts of the same, as will be herein after more fully set forth.

The invention may be carried out in various ways, and I do not limit the invention to any of the specific forms of construction shown.

I also contemplate applying the lift for use between lower and upper floors of buildings. YVhen so used, the devices for allowing and causing lateral movement will be omitted; butit is not necessary herein to show the lift as it would appear when said devices are omitted. In some of the figures of the drawings the shifting devices are omitted for convenience of illustration; but it is to be understood that in practice such devices may be applied in each form in which this invention is embodied. They may also be applied to shift step-ladders.

The accompanying drawings, in which similar reference characters indicate corresponding parts in each of the views in which they occur, illustrate the invention in some of the forms in which it may be carried out.

Figure I is a front elevation of one form of lift embodying my invention in position'besprocket-wheel, and by an air-motor.

fore shelves. Fig. II is a plan of the same sectioned on line II II, Fig. I. The shelves 18 and 19 are omitted for clearness of view. Fig. III is a broken front elevation, partly in vertical section, on irregular line'III III, Fig. IV. The valve-operating lever for controlling the power-medium is shown intact in front of other parts which are shown sectioned in vertical mid-plane. The shifting device is omitted from this View. Fig. IV is a plan section in two planes indicated by lines IV IV, Fig. III. The hose-reel is sectioned on the lower line IV. Fig. V is a broken side elevation, partly in section, showing the operating mechanism and the brake mechanism. The hose-reel is in vertical mid-section. Fig. VI is a broken side elevation, partly in section, of a lift adapted for use with a countershelf. Fig. VII is a broken vertical sectional view of a lift provided with a reservoir for liquid under air-pressure. The shifting device is omitted from this view. Fig. VIII is a horizontal section of the same on irregular line V'III VIII, some of the parts being omitted or broken away. Fig. IX is a similar view of a lift adapted for the use of water. The shifting device is omitted from this view. Fig. X is a fragmental sectional ,view showing safety devices applied to the platform. Figs. XI and XII are detail views of portions of the upper and lower ends, respectively, of the frame for the lifts shown in the other views. Fig. XIII is a sectional elevation on line XIII of the upper rail and rollers shown in Fig. XI. Figs. XIV and XV illustrate in detail the frame-shifting means. In Fig. XIV dotted lines indicate rollers and parts of the cylinder and frame which are omitted to expose the parts shown. Fig. XV is a vertical mid-sectional view of the frame-shifting device constructed to be operated indiscriminately by a belt on the traction-wheel, by a Fi s. XVI and XVII show a modified form of lipright. Fig. XVIII, Sheet 3, is a vertical. sectional view of one form of pressure-regulator adapted for use with my improved lift.

Referring more particularly to the drawings, l and 2 indicate the top and bottom pieces. and 3 and 4 the side pieces, respectively, of the main frame of my improved lift or elevator upon which the operating mechanism is located and may be of any desired shape and material. The frame is movable laterally in front of the shelving 5 by means of rollers 6, which travel along top and bottom guide-rails 7. These rails may he of any desired material and form, although I prefer to make the lower oneof T-shape iron or steel; but the upper rails may be made of iron or wood. In Fig. XIII a desirable form for the upper rail is shown.

It is to be understood that the frame, where practical or convenient, may be inclined toward the shelving sufficiently to cause the weight of top to balance the weight of the operator when on the platform. This will be readily understood without illustration. Where it is not convenient ordesirable to incline the frame, then the weight of the operator is balanced by locating the supportingrollers 6 to one side of the uprights of the frame, as shown in Figs. II and IV.

By use of either of above means the friction on upper guide-rail is reduced to a minimum.

Located upon the frame, preferably substantially midway of the lower portion, is a stationary cylinder 9, within which is placed a piston 10, the rod of which passes through the upper end of the cylinder and is provided with a pulley 11. A cable 12 is secured at one end to the upper portion of the cylinder and passes up over the pulley 11 and has its opposite end secured to a platform 13. The platform projects laterally from the side pieces of the frame and is movable vertically thereon and preferably furnished with antifriction-rollers 14 14 and 15 15. (See Figs. II, IV, and V.) As the weight of the attendant standing upon the platform would have a tendency to cause the platform to bindupon the side pieces, the rollers 14', which engage with the side pieces 3 4, respectively, below the platform, should be larger than the rear rollers 15, while the rear rollers 15 above the platform should be larger than the front rollers 14. Additional strength is secured for the platform, by providing a brace 16 at each end, the upper end of each'brace forming supports for the rollers lat and 15 and the lower end being connected with the platform, near one end thereof.

The lengths of the piston-rod and the cable are so related to each other and to the length of the side pieces 3 and 4. that when the piston is at the bottom of its stroke the platform will stand in convenient position to receive the attendant as he steps from the floor, and when the piston is at the limit of its stroke upward the platform will have been moved vertically a sufficient distance to enable the attendant to reach the top row of shelving.

A fender 17 may be secured to the platform 13 and to cross-tie 57 in front of the cable and piston to prevent accidental contact therewith, and the upper portion of the platformframe is preferably provided wit-h a shelf 18 for the reception of articles, and a bracketshelf 19, either stationary or adjustable, may be secured to one of the braces 16. The lower end of the cylinder may be provided with a support 20, made in the form of a saddle, to en age with the lower cross-piece 2, and the upper end may be braced by means of lateral arms 21, which engage with the side pieces 3 and 4. The upper end of the piston-rod may be steadied in its movements by means of arms 22, which are secured thereto and provided with antifriction-rollers 23, which engage with the side pieces 3 and 4 as the piston-rod is moved back and forth in the cylinder.

The piston is forced upward within the cylinder by any suitable motive-power medium, as air or water, and descends by gravity and the weight of the attendant upon the platform. I 1

The motive-power medium is introduced to the lower end of the cylinder through a pipe 24:, which connects with the source of power, (not shown,) preferably through a hose 25, which is adapted to be wound onto or off of a reel 26 upon the frame or cylinder as the lift is moved back and forth in front of the shelving. Where air is used, the hose is connect ed with the source of supply substantially midway of the length of the track upon which the lift is movable, so that as the frame is moved in either direction from this point the hose will be unwound from the reel, and as it approaches the center it will be automatically rewound thereon by means of a spring 27 in the well-known manner. As the hose is being unwound from the reel it is preferably deposited in a groove 28 in the floor by any suitable means, a fork 29 being shown at one end of the frame and a grooved idle pulley 30 at the other end for this purpose.

The support for the reel is preferably made from a hollow shaft 31, which communicates with one end of the hose 25 at all times and also with the pipe 24:,thereby establishing constant communication between the source of power and the interior of the cylinder at all times. The outer end of the shaft may be supported by means of a brace 32, which is connected at its ends with the side pieces 3 and 4c in such position as not to interfere with the antifriction-rollers 14 l t and 15 15, or thebrace can run up over and to the cylinder, as shown in Fig. V. When water is used, the shaft 31 is divided by a partition 31 and two reels 2b" 26 are mounted thereon and carry two sections of hose 25 and 25 one of which communicates with the inlet 24 and the other with the outlet, as shown in Fig. IX. The reel may be stationary and attached to shelving.

The admission of the motive-power medium to the cylinder is controlled by means of a two-way valve 33 and its exit therefrom by means of a three-way valve 34. These valves may be operated simultaneously or independently, as preferred, and are each adapted to be set so as to control the movement of the platform as desired. I-prefer to operate them simultaneously by means ofalever 35, mounted upon a suitable support, as a pin 36, and connected at one end with the inlet-valve 33 by means of an arm 37 and at the other end with the exit-valve 34 by means of an arm 38. (See Figs. I, III, and IX.) The arms 37 and 38 are operatively connected with the lever, as by means of pins a. in slideway-slots 39. Suitable connections, as wires or ropes 40 and 40, are connected with the ends of the lever and also with another lever 41, which is pivotally connected at the top crosspiece '1. Stops 42 and 42 are secured upon the ropes near the levers 35 and 41, respectively, and are adapted to be engaged by suit-able devices, such as arms 61 6, upon the platform and its frame for automatically stopping the movement of the platform at the upper and lower limits of travel. Ahand-grip 43, preferably collapsible, is placed upon one of the ropes in position to be grasped by the attendant for the purpose of operating the valve to the cylinder for controlling the movement of the platform. The hand-grip 43 may be a section of hose or any other collapsible device by which the wire or rope 40 may be grasped.

' Stops 44 may be adjustably secured to the frame of the lift in position for engaging with and limiting the movement of the ends of the valve-lever 35.

The exhaust-port from the piston may communicate with the top of the cylinder through a by-pass 45 to equalize the pressure above and below the piston and with the interior of the botton cross-piece 2 through a pipe 46, and in case air is the power medium used may communicate also with the open atmosphere through perforations 47. (See Fig. III.) This forms a muffler for the outlet which will prevent any disagreeable noise from being made by the escaping air as the cylinder and platform move in either direction.

, Stops 48and 49 may be adjustably secured upon the top and bottom tracks, respectively, for engaging with buffers 50 on the frame and stopping the lateral movement of the lift in either direction. Brushes or cleaners 51 for the rollers (see Figs. I and XII), may also be adjustably secured to the lower cross-piece 2 in position for moving along the lower railin front of the rollers 6 as the frame is moved upon the track. A suitable hood or casing 52 may be placed over the lower rollers 6, and a guide book or link 53 (see Fig. XIII) may be connected with the upper ends of the side pieces 3 and 4 to connect with the upper trolley or carriage b to avoid any up or down pressure on said carriage in case of any unevenness in the lower track. A wheel 54 may be secured at each end of the bottom cross-piece 2 in position to travel under a guard rail or track 55 (see Fig. V) to prevent the lower rollers 6 from leaving the bottom rail 7. A

convenient means for securing said wheel in position is by extending the axles c of the lower rollers 6 and mounting the wheel 54 upon the rear end thereof.

Slotted sleeves 56 (see Figs. IV and VIII) may be arranged to guard the side pieces 3 and 4 to prevent contact of any person therewith, and such sleeves may extend from the platform up to the tops of the braces 16 to give additional strength thereto and by which the shelf 19 may be supported when light goods are to be handled. A cross-piece 57, Figs. I, II, and IV, may be secured to the upper portions of the braces 16 to give additional strength thereto. The platform may also be provided with a safety device in the usual manner, or said device may consist of a spring 58, (see Fig. X,) which is connected at its center with the cable 12 and rests with its ends against the plat-form 13, cams or eccentrics 59, located upon the under side of the platform in position to engage with the uprights 3 and 4, and controlling-levers 60, which are connected with the spring near its center.

I prefer to provide my lift with braking mechanism, so that when the platform is stopped at any desired point in its vertical travel it may be held there independently of the motive power. One form for accomplishing this is shown in Fig. V, in which a brakeshoe 61 is held in position by a link 61 to engage with one of the side pieces 3 and 4 and is operated by means of toggle-levers 62, the members of which are pivotally secured, respectively, to the brace 16 of the frame and to a resilient devicef on the brake-shoe. One end of the link 61 may be pivoted to the platform of the elevator and the other end pivoted to the shoe 61. The brake may be operated by means of a bent lever 63, which is pivotally mounted upon the brace and has one of its members connected with the toggle-levers 62 by means of a link 64. The con nection 40 may be provided with lower and upper stops 42 and 42, and the connection 40 may be provided with lower and upper stops and 65. The end of the lever carrying the link 64 may extend far enough to be in position to engage with a stop or button 65 on one connection 40. The arm d, the stops 42 and 65, and the brake mechanism are so arranged relative to each other that as the platform nears the lower limit of its movement the arm d engages with the stop 42, thereby shifting the connection 40 and closing the valves 33 and 34 and at the same time bringing the stop 65 into engagement with the extended arm of lever 63, thereby setting the brake-shoe 61 against the upright.

A lever 66 may be mounted so as to swing with the lever 63, being yieldingly held adjacent thereto by means of a spring 67, so that the operator can grasp it with the hand simultaneously with the lever 63. A link or push-rod 68 is pivotally connected with the lever 66 above its pivotal point and has its opposite end provided with a head 69, which extends beyond the end of the lower member of the lever 63 in position to serve as a guide ICO for the rope 40 and to clamp said rope against said arm. A link may be pivotally connected at its ends respectively with the lower arm of the lever 63 and with the hand-grip 43, whereby said lever may be operated by means of the handgrip. As the platform nears its upper limit the upper arm 6 engages with the stop 42, thereby shifting the connections 40 and 40 and closing the valves 33 and 34 and bringing the stop into engagement withthe upper end of the hand-grip, thereby setting the brake. The valve-operating lever 35 and the brake and the valves are so arranged that when the joint of the toggle is above or below the brake the ports to and from the cylinder will be open as desired, according to the direction in which the platform is moved; but when the joint is on a line with the brake the valves will be closed. It is seen that the buttons or stops 42 and 42' on one of ropes 40 are to operate valves and the buttons 65 65 on the other rope 40' are to operate the brake.

If it is desired, the lift may be provided with areservoir 71 (see Fig. VII,) which communicates with the lower end of the cylinder 9 through a port or pipe 72. The inlet-valve 73 communicates with the upper portion of the reservoir by means of a pipe 74. The reservoir may be filled with a liquid, as oil or water, to a level below the opening of pipe 74, and the piston 10 can be forced upward by admitting air through the pipe 74 to the space above the liquid. When the piston is to descend, the air is permitted to escape through the pipe 74 and out through a valve 73, being a three-way, which is operated by means of a lever 76, said lever being connected with the lever 35 by means of a link 77. A valve 75 is located in port or pipe 72 to regulate flow of liquid and is operated by levers 35 and 76. In this manner the liquid (not shown) is alternately transferred from the reservoir to the cylinder and back again without any of it being permitted to escape. It is evident that the reservoir 71 could be supplied with a motive-power medium, as compressed air, which could be controlled by a three-way valve in place of the two-way valve 75, and thereby the permanent connection with a source of power through the hose and reel could be avoided.

My improved lift may be adapted for use with a counter-shelf a. (see Fig. VI) by making the side pieces short enough so that the lower track-rail 78 could be placed upon the top of the counter near its outer edge. A link or arm 79 may be suspended from the lowerportion of the lift-frame and provided with a wheel 80, which runs underneath the counter-shelf and prevents the wheel-frame from leaving the track-rail 78. A supplypipe 81 may extend from its communication with the lower end of the cylinder down below the counter-shelf far enough to receive the hose 25,which is inclosed in a trough or box 94 and is to be drawn back and forth as the frame is moved, the connection of the hose with the source of power being the same as hereinbefore described. The hose box 94 may, if preferred, be located at or near the top of the shelving and connection made to upper end of hollow upright 3 or 4 and also connecting the lower end of said upright to connections under the cylinder. If desired, the box 94 may be used in any of the traveling lifts. A swivel 95 may be provided to allow the elbow at the hose connection to play in either direction.

The lower end of the brace 16 may be extended, as shown at 82, so as to support the platform 13 conveniently close to the floor. A brace 83 may be used at the upper end of the extension to give sufficient rigidity thereto to hold the parts in position.

If it be desired to use a pressure-regulator in the pipe that furnishes the motive power for instance, in a water-main 84 (see Fig. XVIII, Sheet 3)a cylinder 85 may be connected therewith in position to allow a piston 86 in the cylinder to be operated by the water in the main. A lever 87 is pivotally connected at one end with the cylinder by means of a link or fulcrum 88 and with the valve-lever 89 at the other end by means of an adjustable link 90. Lever 89 operates valve 91,which regulates pressure from main pipe 84. The piston g of adash-pot 92 is connected by pivot h with the lever 87 to control or regulate the movements thereof while the apparatus is being operated upon by the pressure of the water in the main. Weights 93 or an adjustable spring, (not shown,) as required, may be connected with the lever 87, according to pressure desired, to return the parts to appropriate position after the motive power has been reduced to desired pressure.

The apparatus may be shifted along the track therefor by hand or by power driven from any available source, the hand-power being provided for use in case the motorpower should be inoperative or not sufficient for the work. The means for performing this work will be readily understood by referring to Figs. XIV and XV. t designates a wheel journaled on the reel-shaft 31 and preferably furnished with a traction-rim j, of rubber or other suitable material, to run on the floor k or on any other suitable support. m n 0 p designate means to transmit power from the wheel 7; to drive the shafts c of the support ing-rollers 6 to drive said rollers in the same direction with the power-transmitting traction-wheel t'j. The part q represents a reversible motor, which may be of any convenient or desired type. r s indicate pipes through which a power medium, such as air, may be alternately admitted to drive an airmotor, as q, in opposite directions. No attempt has been made in the drawings to detail the motor (1, which is connected by a pinion q with wheel m for driving the lift-frameshifting device, the motor being under the control of the attendant at all times.

t designates a rope belt led around a pulley u on the shifting-wheel i and up over pulleys v to be grasped by the user and operated to drive the wheel 2' to shift thelift in either direction.

The wheels 1', n, and p are so proportioned to each other that the rollers 6 will be driven fast enough to keep pace with the wheel 2', and thereby all inequality of speed and friction will be avoided.

In Figs. XVI and XVII the support 41 is T shape in cross-section instead ofround, and the piston-guiding pulleys 23 run alongthe mid-rib or stem of the T, while the antifriction-wheels 14 14' 15 15' run along the arms of the T.

Inusing my improved invention as a traveling lift the parts are arranged in position in front of the shelving to be reached, and the hose is connected with the source of power. When a person wishes to ascend by use of the lift, he may move the frame laterally upon its track to the desired position, step upon the platform or support, grasp the collapsible hand-grip 43, and pull the rope 40' up, thus to operate the shifting-lever to admit motive fluid below the piston and to allow the confined air above the piston to escape. As soon as the operator reaches the desired height he shifts the connection in the opposite direction to shut off the supply of fiuid, preferably without permitting that which is below the piston to escape, and sets the brake mechanism so as to hold the platform stationary. To descend, he may operate the shifting-lever so as to release the brake and operate the valves topermit the fluid below the piston to escape through the by-pass to point above piston. The platform descends by gravity as the fluid escapes, sufficient air remaining under the piston to form a cushion for the descending load.

In lifting articles to place them on a shelf the same may be put upon the shelves 18 or 19 of the support and carried up therewith.

If at any time while the attendant is upon the platform he desires to move laterally without descending, the entire frame can be moved upon its track or support in the same manner as with the ordinary traveling ladders or by a power mechanism, operated by hand or by air, (see Figs. XIV and XV), so that the platform can be moved vertically upon the frame at any desired point.

As above described, it will be seen that my improved lift can be operated easier than the ordinary traveling step-ladder and that it will require no more room or floor-space than the same. It is also evident that it can be made of any desired material, the only requisite being that it have sufficient strength to adapt it for the use or position in which it is intended to be used.

When used as a stationary lift in private dwellings or elsewhere, the frame, composed of parts corresponding to 1 2 3 4, may be stationed in the required position, and a cylinder 9 fixed thereto and extending up and down will be provided,substantially as shown. The carrier, composed of the platform 13 and its frame, will be mounted to move up and down the frame of the lift, which serves as a guide therefor, and the piston be arranged in the cylinderand constructed, as shown, with its rod extending aboverthe upper end of the cylinder and guided by the guides 3 and 4 of the frame, and the rod will be connected with the carrier by suitable means to move the carrier up and down. Preferably the flexible means 12, running over the pulley 11 and fastened at its ends to the carrier and to the frame ofthe lift, will be employed. Any suitable means will be provided to apply fluid-pressure to move the piston upward.

- This construction is therefore specially adapted for use where acompact and easily-operated lift is required.

It is to be understood that I do not limit my invention for laterally shifting the lift from different heights thereon to the exact form of lift shown; but the same may be applied to a laterally-moving frame of any form of lift-such as, for instance, the frame of a step-ladder. (Not shown.) The rope belt 25 can be grasped by the person while at any height on the lift to drive the traction wheel or wheels, including the rollers 6, in one and the other direction to shift the frame along the upper and lower tracks or guides. It is to be understood that in case of any other form of motor to drive the traction wheel or wheels means for controlling the motor from difierent heights on the frame will be provided. Such means will be readily understood by the constructor and need not be shown in the drawings.

The open platform 13 may be furnished with a dress-guard of any suitable form and dimensions open at front to admit the person desiring to use the lift. This guard may be constructed of wire or any other suitable stuff and of any desired height to hold the lower portions of the skirts of females desiring to use the lift.

In Figs. I and II, 130 designates a form of said dress-guard.

It is to be understood that the frame may be furnished with intermediate cross-bars to stiffen the same and that many changes of structure may be made without departing from the spirit of this invention.

In order to avoid any unnecessary weight upon the platform, the dress-guard is composed of two trough-shaped sections, and the same, as shown at 130 in Fig. II, are arranged at the two front corners of the platform with an open space between them through which the person desiring to use the lift may gain access to the platform. The two troughshaped sections 130, together with the fender 17, hold the skirts from projecting out beyond the platform, so that women may use the lift without embarrassment.
